Home Health Agency Performance in the United States: 2011-15.

OBJECTIVES: To evaluate home health agency quality performance.

DESIGN: Observational study.

SETTING: Home health agencies.

PARTICIPANTS: All Medicare-certified agencies with at least 6 months of data from 2011 to 2015.

MEASUREMENTS: Twenty-two quality indicators, five patient survey indicators, and their composite scores.

RESULTS: The study included 11,462 Medicare-certified home health agencies that served 92.4% of all ZIP codes nationwide, accounting for 315.2 million people. The mean composite scores were 409.1 ± 22.7 out of 500 with the patient survey indicators and 492.3 ± 21.7 out of 600 without the patient survey indicators. Home health agency performance on 27 quality indicators varied, with the coefficients of dispersion ranging from 4.9 to 62.8. Categorization of agencies into performance quartiles revealed that 3,179 (27.7%) were in the low-performing group (below 25th percentile) at least one time during the period from 2011-12 to 2014-15 and that 493 were in the low-performing group throughout the study period. Geographic variation in agency performance was observed. Agencies with longer Medicare-certified years were more likely to have high-performing scores; agencies providing partial services, with proprietary ownership, and those with long travel distances to reach patients had lower performance. Agencies serving low-income counties and counties with lower proportions of women and senior residences and greater proportions of Hispanic residents were more likely to attain lower performance scores.

CONCLUSION: Home health agency performance on several quality indicators varied, and many agencies were persistently in the lowest quartile of performance. Still, there is a need to improve the quality of care of all agencies. Many parts of the United States, particularly lower-income areas and areas with more Hispanic residents, are more likely to receive lower quality home health care.
